Description

technical field [0001] The invention relates to the technical field of signal receiving, in particular to a safety TV signal receiving device. Background technique [0002] At present, digital TV has been used in some cities, but in some remote rural areas, the signal quality is poor. People usually install TV signal receivers to receive signals to improve the TV signal quality. However, when the TV signal receivers are installed and calibrated, The adjustment requirements for the orientation and angle are extremely precise. In the prior art, the adjustment of orientation and angle is manually adjusted. Due to the instability of manual adjustment, it is more difficult to adjust the school team, which is not only time-consuming and labor-intensive, but also It is difficult to achieve the ideal adjustment effect, and there are major drawbacks that need to be improved. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide...

[0002] At present, digital TV has been used in some cities, but in some remote rural areas, the signal quality is poor. People usually install a TV signal receiver to receive the signal to improve the TV signal quality. However, when the TV signal receiver is installed and checked, The adjustment of azimuth and angle is required to be extremely precise. In the prior art, the adjustment of azimuth and angle is manually adjusted. Due to the instability of manual adjustment, it is more difficult to adjust the school team, which is not only time-consuming and labor-intensive, but also It is difficult to achieve the ideal adjustment effect, and there are major disadvantages, which need to be improved
